TO DO:

La Gpu con 112 livelli � inutilizzabile, possiamo dividere in integrata e dedicata, oppure dividere per le marche.

@Dario: Per la gpu farei innanzitutto una divisione tra integrata e dedicata, e tra quelle dedicate le suddividerei per VRAM (inizialmente pensavo di cercare dei prezzi per avere una stima quantitativa di quanto valga la gpu dedicata, però bisognerebbe cercare prezzi medi e visto che i modelli son tanti mi pare troppo lavoro e non chissà quanto significativo)

Anche la memoria � problematica, ho gi� estratto la presenza o meno dell’SSD, ma bisogna pensare ad un modo di valutare la memoria.

@Dario: ottimo la divisione SSD/HD, per avere un indicazione quantitativa potremmo cercare il prezzo di un gb di SSD e di un gb di HD da una fonte affidabile, e pesare l’importanza delle dimensioni su questo indicatore, che ne dite?

Quite skewed to the right, mean > media

We could try to apply a correction like Log(Y)

data$LogPrice=log(data$Price)
ggplot(data,aes(x = log(Price))) +
